Fixed a bug in LSH hashtable writing to disk that doesn't always sort the t2 entries into strict weak ordering. Now it does. Lots of debugging informational code inserted.

Fixed upper-limit (T) boundary error in MultiProbe::generatePerturbationSets(x, T). Setting this too high spins algorithm1 into infinite heap allocations without possiblity of terminating. This is now silently capped at --lsh_k * 2; the algorithm halts up to this threshold.

Working version of multiprobe LSH. Passes tests. But needs testing vis-a-vis TP improvement. In the process, found a bug in hash function projections on rare occasions admitting negative values. This only shows for large datasets and was fatal for multiprobe.
